[Tigers] "POS" carb

[Thomas Witt]

As you said you drove a short 6 miles and there was bubbling gas.  If this 
car sat for 30 years the gas tank may be full of debris.  If it is getting 
past the filter (is there a filter?) you could be having particles not 
allowing the float to close.  This might be the cause of the excess fuel.

 So, it is either the float bowls overfilling (particles in the needle & 
seat), overheating ( you need to insulate the carb from the intake with a 
none heat absorbing spacer or your fuel pressure is too high.  Those would 
be the first things to check.
